Ormosia lignivalvis is here first recorded for the Colom- 
bian flora. A very lofty tree with a beautiful cylindrical 
trunk two feet in diameter and a light reddish brown 
bark, it is known as ‘‘cocho’” by Colombian settlers of 
the Amazon who employ a strong infusion of the bark 
for washing sores with pus. The same informants con- 
sider the black and scarlet seeds to be poisonous.

A small but beautiful tree of the central and north- 
western Amazon, Ormosia macrophylla is valued by the 
Tawaino Indians of the Rio Kananari of Amazonian 
Colombia as one of the ingredients in a curare prepared 
reputedly from the bark of a Strychnos, the bark of Vo- 
chysia ferruginea Mart., the crushed stems and leaves of 
an aroid (possibly a Philodendron) and the bark of Or- 
mosia macrophylla. 1 did not witness the preparation of 
this curare, but several independent informants agreed 
on the ingredients of the preparation. 
The tree is known as ‘‘peonia’’ amongst the civilized 
settlers of the Rio Vaupés. In Tawaino, it is called 
ma-hi'-ke.
